Ok, to not get more thread drift on the OP, and get more exposure on this subject stemming from this post:
As @Oh Shoot correctly stated, it is legal to have a loaded pistol or long gun in your vehicle, but the hunting regulation seems to contradict that. From page 36 of last years (2017) regs:
The first sentence seems to support the transporting part with "except when authorized ", but then goes on to prohibit them being loaded. Now, you would think that a law would supersede a hunting reg and you would have to be hunting for this to apply...but I can tell you from personal experience that the judge will take the game warden's word over yours if charged. And though this may be a reg, there seems to be "law" behind it as many game infractions are misdemeanors. Now, don't get me wrong, I support many of these hunting regs, but game wardens get too much leeway in the enforcement of them and there are too many loosely worded regs, and laws, which can be seen in different ways.
